COOKER.

Application filed May 5,1915. Serial No. 26,107.

1 0 all whom it may concern j Be it known that 1, WILLIAM H. Perensnx, acitizen of the United States, residing at Lincoln, in the county ofLancaster and State of Nebraska, have invented new and usefulImprovements in Cookers, of which the following is a specification.

This invention contemplates improvements in cooking vessels, and has torits object the provision of a device of this character constructed toconfine the heat therein with a view of thoroughly cooking the food incomparatively short order, under high pressure. with means forregulating the pressure to permit certain foods to cook slowly whendesired.

Other objects will appear as the nature of the invention is betterunderstood, the same consisting in the construction, combination andarrangement of parts hereinafter more fully described and particularlypointed out in the appended claim.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views and wherein Figure1 is a. side view of the' vcssel constructed in accordance with myinvention. Fig. 2 is an end view thereof. Fig. 3 is a sectional viewtaken on line 3-3 of Fig. 2.

Fig. 4 is a detail sectional view of the pres-.

sure valve.

' Referring more particularly to the drawing by numerals, 5 designatesthe body portion of the vessel which may be constructed of any suitablematerial and design, the

.cover therefor being indicated at 6. The

upper edge of the vessel is provided with a groove 7 for the receptionof the gasket 8, the outer edge of the cover being flared as at 9, theflared portion thereof being adapted to-be seated upon said gasket toprovide a fluid tight joint between the vessel and the cover when thelatteris in operative position. Projecting from the opposite sides ofthe vessel at diametrically opposite points are the lugs 10 upon whichthe hook-like terminals 11 of the bail 12 are pivotally mounted, thelatter being supported upon the rest 13 in normal horizontal position atone side of the body of the vessel.

Rising centrally from the cover 6 is a truss 14:, disposed transverselywith respect thereto and extending across the entire width of the cover,the upper edge of the truss being formed with a groove 15 for thereception of the bar 16, which has. apertured Specification of LettersPatent. Patented June 2'7, 1916.

cars 17 arranged at its opposite ends through which the rods 18 areextended, the latter terminating at their lower ends in hooks 19eccentricall connected with the hook-like portions 0 the bail 12, whileadjustably mounted on the upper ends of the rods 18 are tensioning nuts20. i

By reason of the construction and specific arrangement of partshereinabove described it will be noted that the bail 12serves in thecapacity of a locking lever, Operating a; to draw the cover downwardlyinto efiective engagement with the body 5 and to retain the same inposition thereon, when the bail is lowered, and to release said parts onmovement of the bail in an upward direction. It is to'be understood thatthe cover is only to be used when it is desired to use the vessel as ahigh pressure cooker, at which time the heat, and flavor extracted fromthe food is confined withinthe vessel, whereby the food is properly andthoroughly cooked in'compar'atively short order, with a minimum amountof fuel.

A safety pressure valve rising from the cover is indicated at 21 andcomprises :1 cylindrical casing 22, having an exteriorly threadedreduced lower portion 23 threaded in a suitable opening in'the cover 6and secured therein by means of the nut 24 as shown. The casing isprovided with a reduced bore 25 and an enlarged bore 26, forming a valveseat 27 therebetween, and within the latter is mounted a spring pressedvalve 28, the stem 29 of which projects end bearing against the valve'28and itsopposite end against the nut, 30, and operates to normallymaintain the valve upon its seat. Obviously the tension of this springcan be easily regulated by means of the adjusting nut 30. When thepressure within the vessel reaches a predetermined height, the valve 28is forced upwardly from its seat, thereby permitting escape of steam orthe like through. the vent 32 in the casing immediately above the seat27.

However with a view of regulating the pressure within the vessel topermit certain foods to be cooked slowly when desired, I employ aneccentric lever 33 pivoted to the stem 29 above the adjusting nut 30 andhaving its actuating portion 34 engaging the latter. By operating thislever it will be n'ianifest that the valve may be held in openedposition to permit escape of the steam or the like through the vent 32.This lever may be further operated to open the valve to permit escape ofthe steam or the like prior to draining the water from the vessel whenthe latter is. used intlie capacity of a high pressure cooker.

It is believed that from the foregoing description the nature andadvantages of the invention will be readilywpparent without; requiring amore extended explanation and therefore the same has been omitted.However I desire to have it understood that vari-- ous changes in theconstruction and arrangement of parts may be resorted to when desired asfall within the scope of the appended claim.

llhat is claimed is:-

In a cooking vessel, the eoiiihiiiation \\lill a swinging hail, oi acover therefor, a truss rising llOlll said titfltlitlllli having alongitiidiiial groove therein, a clamp liar arranged within the grooveand having aper-. tlii'ed ends pro ecting beyond the sides oi the cover,and hook-like iiieiiiliers passed through said apertures andadjiislalily associated ,\\'ith said liar. and eeeeiili'ieally connectedwith said bail for the purpose (.lesei'ihed.
